1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeThe efficacy of pre or postoperative chemotherapy for resectable colorectal cancer liver metastases (CRLM) is disputed. This study aimed to examine the risk factors for time to surgical failure (TSF) and analyze the efficacy of pre or postoperative chemotherapy prior to liver resection for CRLM.

methodsThe clinicopathological factors of 567 patients who underwent initial hepatectomy for CRLM at 7 university hospitals between April 2007 and March 2013 were retrospectively analyzed. The prognostic factors were identified and then stratified into two groups according to the number of preoperative prognostic factors: the high-score group (H-group, score 2-4) and the low-score group (L-group, score 0 or 1).

resultsPatients who experienced unresectable recurrence within 12 months after initial treatment had a significantly shorter prognosis than other patients (p < 0.001). Multivariate analysis identified age ≥ 70 (p = 0.001), pT4 (p = 0.015), pN1 (p < 0.001), carbohydrate antigen 19-9 ≥ 37 U/ml (p = 0.002), Clavien-Dindo grade ≥ IIIa (p = 0.013), and postoperative chemotherapy (p = 0.006) as independent prognostic factors. In the H-group, patients who received chemotherapy had a better prognosis than those who did not (p = 0.001).

conclusionPostoperative chemotherapy is beneficial in colorectal cancer patients with more than two of the following factors: age ≥ 70, carbohydrate antigen 19-9-positivity, pT4, and lymph node metastasis.
